Computers in a Changing World

Many scientific and technological advances mark the beginning of the

twentieth century. These advances include inventions such as airplane,

television, and most especially the computer. Computers are changing our

lives, they are sweeping away the old ways of doing things with their superb

speed and reliability.

As many of today’s basic functions are being simplified by technology,

computers have been on the forefront in developing innovations through its

many functions.

In this digital world, having the knowledge and skills in computer

servicing is the start and most fundamental of all.

Years ago… Today…

We use calculator to compute. It

takes some time to solve huge

amount of numbers.

We use computers to solve billions of

math problems.

We use landline telephone to call our

friend.

We use mobile phones to call anyone

anywhere.

What is It

www.google.com

www.google.com www.google.com

We send our mails through post

office. It takes several days to

received.

We send messages through the

computer. It takes only a few seconds

before they are received.

We go to the library to look for

information in books.

We search information on the

internet.

I. Computer and Its Types

A computer is an electronic machine that processes and stores

information. It takes in raw information using input devices, stores in the

memory until it is ready to be processed in the processing unit and sends out

results using output devices.

Computers are classified into four (4) different types based on its

processing power and size:

THE TYPES OF COMPUTERS

1. Supercomputer is the fastest and most powerful computer in terms of

performance and data processing. It uses its power to run one program at

a time.

Used in:

Research and exploration

Weather forecasting

Nuclear weapon testing

2. Mainframe computer is not as powerful as the supercomputer. It is

designed to run multiple programs concurrently. It is commonly used in:

Banks

Educational Institution

Insurance companies

3. Minicomputer, also known as “Midrange” computer fill the space between

the mainframe and microcomputer. It is smaller than Supercomputer or

Mainframe computer but bigger and more powerful than the microcomputer.

They are generally used as mid-range servers.

Some of its uses are as:

Data Management device

Communications Portal

Process Control

coolant, where it is dissipated away from the device, thereby allowing

regulation of the device's temperature.

c. Optical Drive - An optical drive is a storage device that uses lasers to

read data on the optical media. There are three types of optical drives:

Compact Disc (CD), Digital Versatile Disc (DVD) and Blu-ray Disc (BD).

D. STORAGE DEVICE stores data and programs. These hold data,

information, and programs permanently.

D.1. Magnetic Storage

D.1.1. Hard Disk Drive (HDD) - also known as hard drive, is a magnetic

storage device that is installed inside the computer. The hard drive

of the system

b. System Programmers – are people who write codes and programs to

implement the working of the system.

c. System Operators – are people who operate the system and use it for

different purposes. Also called the end users like students, teachers, and

other professionals.

III. HOW THE COMPUTER WORKS?

Data are raw facts about things, events, or activities that are captured,

recorded, and stored on the computer. These can be in the form of words,

numbers, or pictures.

Data become information when these have been arranged or

organized to be of use and to have meaning to the user.

INPUT – in this step, data are entered into the computer through input

devices, such as keyboard and mouse.

PROCESS – is the computer’s method of analyzing, managing, or

manipulating data. The data entered into the computer undergo

changes. The Central Processing Unit (CPU) directs the operation

of the input and output devices to create the needed information.

OUTPUT – You get the output once the computer is finished processing the

data. It could be displayed on the monitor, printed on paper, or

heard through speakers.

www.google.com

16

STORAGE – The processed data are kept for future use. We use Hard Disk

Drive to store the information.

IV. Common Computer Applications Used in Performing Computer

Related Duties

1. Microsoft Office Application – is a package application developed by

Microsoft and is intended to be used in offices and schools.

a. MS Word – A word processing application used for creating

documents such as letters, brochures, activity programs, and

learning activities.

b. MS Excel – is a spreadsheet program ideal for entering, calculating,

and analyzing numeric data such as sales figures, sales taxes, and

students’ grades.

c. MS PowerPoint – is a presentation tool that uses graphical approach

to presentation in the form of slides. Its primary function is to help a

presenter deliver its presentation effectively.
